Tom O'Callagahan, a bartender at Jimmie Steiny's, is the conductor of this engine, welcoming all aboard.

North Shorites can start from Steiny's in St. George at 11 a.m. Or, meet the whole crew at noon in Joyce's Pub, Eltingville, which is putting out a free breakfast spread. "This way we have some food in our stomach," says O'Callagahan.

The train pulls into Talk of the Town in Great Kills at 1 p.m., the Corner House in Grant City at 2 p.m. and Lee's Tavern at 3:05 p.m. The wreck crashes at Steiny's at 4:20 p.m., where revelers can go for a free buffet of meatloaf, pasta and salads, and celebrate Kentucky Derby day with $5 mint juleps.

Part of the beauty is, the only driving anyone has to do is to the starting and finishing points, a rare thing in this car-happy borough.

O'Callagahan and Danny Nemeth, a bartender at Danny Blaine's, hatched the plan a couple of months ago, recalling a pub crawl that happened nearly six years ago by train.

"It was a lot of different people from different places that didn't particularly know each other and by the end of the train crawl everyone knew each other," says O'Callaghan.
